Abstract
The utility model discloses an anchor rope anchoring end device with reversely-outward claws. The anchor rope anchoring end device comprises an end reversely-outward claw, a hollow sleeve tube and a nut. Left-hand threads are arranged outside the end reversely-outward claw. The upper end of the end reversely-outward claw is provided with the two reversely-outward claws. An inner hole where the hollow sleeve tube can pass is formed in the solid lower end. One end of the hollow sleeve tube is evenly provided with external threads, and the nut can be installed at the end of the hollow sleeve tube. The anchor rope anchoring end device with the reversely-outward claws is simple in structure, and installation and matching of other devices are not needed when the anchor rope anchoring end device is used.
Description
Technical field
The utility model relates to mine working engineering apparatus field, particularly a kind of with anti-outer anchorage cable anchoring end device of grabbing.
Background technology
Anchor cable is, by backing plate, anchor tail is fixed on to surface, tunnel, and the other end (anchor head) is fixed in the deep rock mass of roadway surrounding rock the prestress wire through slide surface.Anchored end need to fully be rubbed Anchor Agent, and is convenient to strengthen anchoring effect.At present, in prestressing anchor support construction, anchored end is just put into boring by anchor cable head, is pushed into foot of hole and smashes Anchor Agent by abundant stirring, reaches the effect of integral fastening, and the method application is convenient, very general.But, this common anchor cable is when stirring Anchor Agent, due to anchor cable friction less, intensity is low and the reason such as construction, cause anchorage cable anchoring agent to be stirred inhomogeneous, affect anchoring effect, thereby anchor cable can not be played one's part to the full and finally may occur to be out of shape with country rock, tunnel being lost stable.
Summary of the invention
The above-mentioned technical problem existing for solving prior art, the utility model provides a kind of and can effectively rub Anchor Agent and can become firm whole anti-outer anchorage cable anchoring end device and the anchoring process of grabbing of band that improves fastness with Anchor Agent.
The technical scheme that the utility model solves the problems of the technologies described above is: the anti-outer anchorage cable anchoring end device of grabbing of a kind of band.This anchorage cable anchoring end device comprises that end anti-outer is grabbed, hollow sleeve and nut.Outside described end is anti-, grab outside and be carved with left hand thread, there are two anti-outer pawls upper end, has an endoporus that can pass through for hollow sleeve in the entity of lower end; External screw thread is all carved with in hollow sleeve one end, can supply mounting nuts.
With an anti-outer anchoring process of grabbing anchorage cable anchoring end device, the steps include: the assembling of (1) anchor end of anchorage cable position device: first hollow sleeve is put into the anti-outer endoporus of grabbing in end, then anchor cable is inserted in hollow sleeve; Then push hollow sleeve pipe end anchor cable head aside a segment distance, add steel wire again to screw and make butt end anchor cable; Fastening nut applies pretightning force again;
(2) adopt the boring of spudding in country rock inside of the hammer drill, drilling rod and the drill bit that are equipped with mutually with anchor cable;
(3) clean up boring, Anchor Agent powder stick is put into boring, then the anchorage cable anchoring end device assembling is put into boring immediately following Anchor Agent;
(4) anchorage cable anchoring end device is sent into foot of hole, anchoring cartridge can be followed and enter foot of hole;
(5) utilize table type rock drill to drive anchor cable rotation that Anchor Agent is rubbed;
(6) utilize draw-off gear to apply prestressing force to anchor cable, tray and nut.
The beneficial effects of the utility model are: 1) simple in structure, the installation without other devices during use coordinates; 2) whole apparatus for assembling is inserted boring, has realized abundant rubbing Anchor Agent, and can make itself and Anchor Agent fully in conjunction with strengthening anchoring effect, overcome traditional anchoring method only anchor cable head can not fully rub Anchor Agent and the not high defect of anchoring firmness; 3) whole apparatus for assembling all adopts steel metal, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Fig. 2 is the schematic diagram of the utility model in work progress.
In figure, 1. end anti-outer grab, 2. hollow sleeve, 3. nut.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details, but the utility model is not limited to this.
As shown in Figure 1, a kind of band anti-outer grab that anchorage cable anchoring end device includes that end instead grabs 1 outward, hollow sleeve 2 and nut 3.Outside end, grab 1 outside and be carved with left hand thread, there are two anti-pawls lower end, has an endoporus that can pass through for hollow sleeve 2 in the entity of upper end; External screw thread is all carved with in hollow sleeve 2 one end, can supply mounting nuts.
In work progress, utilize the anti-outer anchoring process step of grabbing anchorage cable anchoring end device of band to be:
(1) complete the assembling of anchor end of anchorage cable position device: first hollow sleeve 2 is put into anti-outer 1 the endoporus of grabbing in end, then anchor cable 4 is inserted in hollow sleeve 2; Then push 4 of hollow sleeve 2 end anchor cables aside a segment distance, add steel wire again to screw and make butt end anchor cable 4, prevent that anchor cable 4 from coming off in hollow sleeve 2; Fastening nut 3 applies pretightning force again;
(2) adopting the hammer drill, drilling rod and the drill bit that are equipped with mutually with the anchor cable diameter that spuds in country rock inside is the boring (being the anchor cable of Φ 15.4mm and Φ 17.8mm mainly for specification) of 32mm or 28mm;
(3) after boring cleans up, Anchor Agent powder stick is put into boring, the anchorage cable anchoring end device assembling is put into boring immediately following Anchor Agent;
(4) anchorage cable anchoring end device is sent into foot of hole, anchoring cartridge can be followed and enter foot of hole;
(5) utilize table type rock drill to drive anchor cable rotation that Anchor Agent is fully rubbed, abundant to guarantee anchored end anchoring;
(6) utilize draw-off gear to apply prestressing force to anchor cable, tray and nut.
So just completed the anti-outer anchoring of grabbing anchorage cable anchoring end device of band.
